IMPROVEMENT IN PORTABLE FURNACES.

Specification forming part of Letters Patent No. 40,570, dated November10, 1863.

To all whom it may concern:

Be it known that I, ALBERT MAGEE, of Lawrence, in the county of Essexand Commonwealth of Massachusetts, have invented a new and ImprovedPortable Furnace; and I do hereby declare that the following is a fulland exact description thereof, reference being had to the accompanyingdrawings, and to the letters of reference marked thereon.

Figure 1 represents a side "iew of the furnace. Fig.2 represents aninterior side view. Fig. 3 represents a vertical view showing grate, &c.Fig. 4 represents a vertical view showing cover.

My furnace is made to be used in connection with astove, and is so madeas to allow the part A to rest on the top of the stove, while the part Bpasses down through one of the openings in the stove. O is a grate,situated in the lower part of B, on whichthe fuel is placed. 1) is akettle of the common kind, placed in the opening E, reaching nearly tothe fuel. F is an air-conductor, which serves to conduct fresh air downunder the fuel.- The outside opening is above the top. of the stove.Theinside opening is below the grate. Its use is to furnish air tosupport the flame. G is a flue to conduct to the stove and chimney thesmoke, gas, 85c. Now, when the fuel is placed on the grate O andignited, the air rushes in through the air-conductor F down under themake the heat oppressive, and, it being set in the stove, as described,a way is provided for the escape of gas, smoke, &c., into the chimney,instead of into the room.

The superiority of my invention over all others that have been tested isthat I conduct the fresh air down under the fuel, thus making the flamerise up around the kettle, instead of allowing the air to rush in ontothe flame and driving it down, thus preventing the heating of the waterin the kettle.

.I claim The combination, in a portable furnace, of the inductioncold-air flue F, smoke-exitflue G, and grate (3, when constructed to beused as a utensil upon a cooking-stove or range, substantial] y asdescribed.
